In other words, a few months ago, the military did not dare to withdraw the troops because of the eight guts, but since the order to stop the encirclement and suppression of giant ants in the northern capital, the situation in the ant-occupied area has been very stable, which has given the military enough confidence.

When the Mid-Autumn Festival is approaching, the temperature in the north drops unusually obviously, and the temperature at night is even only a few degrees above zero, and in another month and a half, the temperature at night will fall below the zero line.

The cold is an invisible insect killer, and both giant ants and giant locusts will lose their survival base in the realm, and it will never be able to expand on a large scale as in the middle of summer.

"Can't really survive the winter?" Ye Han expressed doubts about the theory of low-temperature insecticide, "Insects can grow the size of a car, in case they mutate into some strange structure, they can withstand the low temperature in winter!" ”

"That's impossible." Xu Ruolin said, "This result is studied by the Northern Capital, and it takes a lot of time for organisms to adapt to the environment, and the body structure of insects is not cold-tolerant, and they can't adapt to low temperatures for thousands of years...... I didn't listen very carefully, was that what I said at the time? ”

Lu Qingzhi and Gao Bo nodded together, only Long Jianguo was expressionless, not knowing what he was thinking.

Xu Ruolin, who had a positive harvest, continued: "The insects either hibernate in winter, or the insects die for the winter, and there is no third choice. ”

Ye Han asked suspiciously, "Listen?" Where did you hear it? ”

"The document sent above, read on the radio." Xu Ruolin's gaze fell on Long Jianguo, "Battalion commander? ”

Long Jianguo nodded: "The document is in the command car, I want to see it taken by myself." ”

Ye Han hurriedly nodded: "That's okay, I'll go now!" ”

"Get out!" Long Jianguo kicked angrily.

Ye Han ran away with a smile, slipped into the command car, and the communication soldier on duty asked Ye Han what he meant, and immediately found a document from the few documents, turned to the last few pages and handed it to Ye Han: "This is it!" ”

Ye Han couldn't help but roll his eyes, the so-called report was actually an attachment to a document!

After taking the document in the hands of the signal soldier, the title of the attachment was very inconspicuous: The effect of temperature on the insect plague.

His gaze skipped over the first paragraph full of clichés, fell directly to the text, and sat directly in the command car to read carefully.

The gist of the text is that the scientific research department of the Northern Capital has long begun to pay attention to the physiological condition of the giant insect, and through rigorous experiments, the research department has come to a conclusion: although the giant insect has changed its body size greatly, the change in body structure is very small, and it is still an ectothermic animal, and its dependence on environmental temperature is extremely high.

In other words, when the temperature is high, it is active, and when the temperature is low, it is less active or even inactive.

According to the experimental results, when the temperature drops to about minus 7 degrees, the activity ability of the giant ants will decrease significantly, and the activity will completely stop at about minus 4 degrees, and quickly enter a state of hibernation.

Normally, hibernating organisms possess a range of physiological abilities to combat cold, such as slowing the heartbeat, lowering body temperature, reduced or even inactive activity, plus prolonged sleep.

At present, the insect plague in the north is mainly three giant insects: giant ants, giant locusts and giant cockroaches.

The report classifies three typical giant insects.

The first is the giant ant, the habits of the giant ant are similar to the ant, the experiment found that the original physiological structure of the giant ant has been unable to adapt to the external climate change, due to the substantial increase in size, the thickened chitin carapace can play a certain role in heat preservation, so the giant ant still has the ability to move around seven degrees, and the ordinary ant will enter hibernation when the temperature is lower than 10 degrees.

In this respect, the giant size of ants does bring certain advantages, but the experiment also found that if the temperature in the simulated environment is reduced to below zero, and the temperature is raised to above zero for a period of time, only a quarter of the hibernating giant ants can still wake up, and if the freezing time is extended, the number of resuscitated giant ants will further decline!

Ye Han saw this, and suddenly thought of the famous liquid nitrogen frozen goldfish experiment, although he did not understand the principle of this experiment, but he had heard a saying, that is, the reason why money can be revived after being frozen by liquid nitrogen is because the size of goldfish is very small, low temperature can quickly freeze goldfish, and the water in the goldfish's body does not have time to crystallize, and it will not destroy the cell structure.

However, the body size of humans and other large animals is too large, and the low temperature cannot quickly reduce the temperature inside the body, and the temperature difference between the inside and outside of the body is too large, and the result is that the water in the cells is frozen.

It is common knowledge that water in cells will become larger when it freezes, and once the water in the cell freezes, it will burst through the cell wall, causing irreversible damage.

As a result, people are frozen to death, rather than being thrown into the water like a goldfish and brought back to life.

Some people may say that if you throw people into the water, even if you could have survived, you will drown in the water.

Ye Han completely disagrees with this, because when he was very young, he had seen a news that a mouse was moving freely in liquid, and even if it still does not reach the level of human application, it will definitely be able to achieve human liquid respiration in the near future.

The key issue is also the process of freezing, not the method of resuscitation.

Retracting his divergent thinking, Ye Han refocused his attention on the report.

According to the report, ants do not sleep until spring, and honestly stay in their holes to reduce their activities and eat stored food for the winter.

Experts in the northern capital believe that the ecological environment in the north has been severely damaged by insect plagues, and the predators of giant ants are extremely scarce, and they doubt that giant ants can get enough food in autumn, and speculate that the ant colony is likely to become extinct due to lack of food during the long winter.

Based on the above two points, experts in the northern capital believe that as long as they persist until the arrival of winter, the problem of giant ants will be completely eradicated.

Ye Han's brain is not stupid, and he immediately thought of the point of view in this report, which is likely to be the key factor for the military to evacuate the ant-occupied area, if there is no conclusion of this report, the ant north area will definitely still be under the strict supervision of the military, and there will definitely be no ant colony out of control.

Presumably, the military has already regretted the loss of control of the ant colony, and the person who used this report as the basis for deciding to withdraw the army, or even the person who wrote the report, will inevitably become a victim of the loss of control of the ant colony.

is originally directly responsible, who will bear the blame if these people don't take the blame?

As for the giant locusts, this thing has no ability to hibernate at all, and the drop in temperature in the north is the direct cause of the locust swarm's southward migration.

If the giant locusts do not cross thousands of kilometers to reach the warm south before winter arrives, they will be doomed.

That is, as soon as it enters winter, or even as long as it enters late autumn, the thriving insect swarms in the north will enter a dormant period!

However, the ovipositor of an ordinary locust can be twice as long as its body length, which means that a locust five centimeters long can lay eggs ten centimeters deep underground!
